[Linux] crosstool-ng 빌드시 'Retrieving needed toolchain components' 에러 디버깅

https://docon.tistory.com/122 에서 crosstool-ng을 설치하고, arm-cortex_a8-linux-gnueabi 툴체인을 선택해, 몇가지 사항들을 바꿔준 뒤 툴체인을 빌드하였다. 그러나 빌드 명령을 입력하니 아래와 같은 오류가 떴다.

로그를 보아하니, `isl-0.20을 retrieving하는 과정에서의 download failed`가 원인이다.

 

crosstool-ng 빌드 이슈(https://github.com/crosstool-ng/crosstool-ng/issues/1625)에 의하면, 해당 오류는 crosstool-ng-1.24.0(현재 내 버전)이 릴리즈된 이후 필요한 packages의 호스팅이 옮겨져서 발생하는 오류라고 한다.

 

이를 고치는 방법은 간단히 master branch에서 빌드를 하면 된다고 한다.

 

따라서 기존 crosstool-ng를 삭제하고 master branch에서 다시 빌드를 시도해보았고, 문제가 잘 해결되었다.
